## DIAGNOSTICS
    Error: $object is not a collection.
        The first argument is an object, but not of a class which extends
        [User::Identity::Collection](https://www.chedong.com/phpMan.php/perldoc/User%3A%3AIdentity%3A%3ACollection/markdown).

    Error: Cannot create a $type to add this to my collection.
        Some options are specified to create a $type object, which is native to this collection.
        However, for some reason this failed.

    Error: Cannot load collection module for $type ($class).
        Either the specified $type does not exist, or that module named $class returns compilation
        errors. If the type as specified in the warning is not the name of a package, you specified
        a nickname which was not defined. Maybe you forgot the 'require' the package which defines
        the nickname.

    Error: Cannot rename $name into $newname: already exists
    Error: Cannot rename $name into $newname: doesn't exist
    Error: Creation of a collection via $class failed.
        The $class did compile, but it was not possible to create an object of that class using the
        options you specified.

    Error: Don't know what type of collection you want to add.
        If you add a collection, it must either by a collection object or a list of options which
        can be used to create a collection object. In the latter case, the type of collection must
        be specified.

    Warning: No collection $name
        The collection with $name does not exist and can not be created.

    Error: Wrong type of role for $collection: requires a $expect but got a $type
        Each $collection groups sets of roles of one specific type ($expect). You cannot add objects
        of a different $type.
